いて２つの切替回路を必要とする。In FIG. 1, if the subscriber's telephone 10 remains on the hook while it is busy, a switching circuit 11ot provided in the line circuit 11 is operated to prompt the subscriber to hang up the telephone, and the howler sound sending circuit 13 is switched off. A howler sound is sent to the subscriber telephone 10. Further, the subscriber line test circuit 14 operates the switching circuit 111 provided in the line circuit 11 to detect batteries and test crosstalk in the subscriber line. In this case, two switching circuits are required for one line circuit.

になシ、頗る経済的なライン回路を実現することができ
る。In order to improve this point, as shown in FIG. The switching circuit 210t provided in the circuit 21 is operated, and when performing a subscriber line test, the switching circuit 210 provided in the subscriber circuit 21 and the switching circuit 255 provided in the subscriber line testing device 25 are operated. In this case, by providing only one switching circuit for one line circuit, it is possible to send out howler sounds to subscriber telephones and perform subscriber line testing, which makes it possible to create a highly economical line circuit. It can be realized.
本発明は以上説明し念ように、ライン回路に設けられる
切替回路の数を従来に比較して半減することができるの
で、頗る経済的なライン回路を得る効果がある。As explained above, the present invention can reduce the number of switching circuits provided in a line circuit by half compared to the conventional one, and therefore has the effect of obtaining a highly economical line circuit.
